Creating AI illustrations for a storybook gets more challenging when two characters share a scene. Their faces, outfits, and proportions need to stay recognizable as they move, interact, and appear on later pages. With Neolemon, you can reuse each character's reference image and describe what they're doing together. We'll follow Amy and Leo through a few scenes, showing you how to set up your characters, write scene prompts, and fix details that get mixed up.

Why AI Mixes Up Characters in the Same Scene

In a scene with two characters, an image generator may put one character's hair, clothes, or accessories on the other. A prompt such as "two children wearing blue and red" leaves it unclear who wears which color. Give each character a separate reference and describe them individually.

The result? Characters that swap features, merge appearances, or simply look different from scene to scene. We cover this problem in depth in our guide on how to keep AI characters consistent, but multi-character scenes add an extra layer of complexity. If you're still deciding how big your cast should be in the first place, our guide to multiple characters in a picture book covers how many characters a story can actually carry, which makes the consistency work below much easier.

Which Neolemon Tool Should You Use?

Use Multi Character Pro to compose an image with recurring characters. Use Story Scene Pro when you also need background, object, layout, or style references. Both let you build scenes around your characters, then make specific changes with Editor Pro.

Start with 20 free credits, no card required. Each image generation or edit costs 4 credits.

Add your character references, describe the scene, and review the result

Step 1: Save a Reference Image for Each Character

Everything starts with your character reference images. These are the foundation that every scene builds upon.

Give each character a clear name in your notes and use it throughout the examples. Here, Amy is the girl with orange hair, a blue coat, a pink beanie, and a red bag. Leo is the boy with brown hair, a red striped shirt, and khaki shorts.

For each character, you need a high-quality image that shows:

Full body view: The AI needs to see the complete character, from head to toe. This includes their proportions, posture, and how their outfit fits their body.

Front-facing pose: A clear, straight-on view works best. Dynamic angles can be added later, but your reference should show the character in a simple, readable pose.

Clean background: A solid color or simple gradient keeps the focus on the character. Busy backgrounds can confuse the AI about what elements belong to the character versus the environment.

Consistent style: Both characters should match in artistic style. Mixing a watercolor character with a Pixar-style character will create visual chaos in your scenes.

If you need reference images, create each character separately in Character Turbo. Ask for a full-body, front-facing pose on a plain background. Watch our step-by-step Character Turbo tutorial to see exactly how it works.

Pro tip: Spend extra time getting your reference images right. It's much easier to regenerate a reference image than to fix consistency problems across 20+ story illustrations.

Step 2: Write AI Prompts for Multiple Characters

Write the prompt in three parts: who each character is, where they stand, and what they do. Keep each action tied to a named character.

Part 1: Identify Each Character

Match each name to a reference image and a few visible details. For example: "Amy is the girl in the blue coat and pink beanie. Leo is the boy in the red striped shirt and khaki shorts. Keep each character's face, hair, and outfit matched to their reference".

Part 2: Set Positions Before Actions

Before describing what your characters are doing, tell the AI exactly where each character should be in the scene. Spatial relationships need to be established before adding complexity.

Examples:

"Amy stands on the left side of the image. Leo stands on the right, one step behind her."

Clear positions make the intended arrangement easier to describe and check.

Part 3: Give Each Character an Action

Amy holds out a wrapped gift with both hands. Leo reaches toward it with his right hand. They look at each other and smile.

Describe each character, their position, and their action.

Step 3: Set the Background

Multi Character Pro has no background field, so describe the setting in the scene prompt.

Pro tip: If you need a specific background, or the same place across several pages, use Story Scene Pro instead. It has the same character upload slots for multiple characters, plus a Background slot. Upload your background once and reuse it whenever the story returns to that location, so the setting stays consistent from page to page. Our Story Scene Pro guide walks through it step by step.

Examples:

"a magical forest"

"in a beautiful park"

"a cozy living room with warm lighting"

"a sunny beach at sunset"

Example Prompts for Two Characters in the Same Scene

Attach Amy's and Leo's reference images before using these prompts. Multi Character Pro gives each reference an @handle under its thumbnail (@character1, @character2 by default). Rename them to @amy and @leo so they match your story, and use those @handles in the scene description when you want to point at a specific reference. Plain names also work, as in the prompts below.

Example 1: High-five in a forest clearing

Use the supplied references for Amy and Leo. Amy, wearing her blue coat and pink beanie, stands on the left. Leo, wearing his red striped shirt and khaki shorts, stands on the right. Amy raises her right hand and Leo raises his left hand for a high-five. They are in a forest clearing. Keep their faces, hair, outfits, and accessories matched to their references.

Example 2: Eating Ice Cream in the Park

Use the same Amy and Leo references. Amy sits on the left side of a park bench, holding a strawberry ice cream cone. Leo sits on the right, holding a chocolate cone. They smile at each other. Keep Amy's blue coat and pink beanie, and Leo's red striped shirt and khaki shorts.

Example 3: Dynamic adventure scene

Use the same Amy and Leo references. Amy stands in the left foreground, pointing toward a cave entrance with her right hand. Leo stands behind her on the right, looking toward the entrance. Amy looks excited; Leo looks cautious. Keep both characters' faces, hair, and outfits matched to their references.

Example 4: Emotional storytelling moment

Use the same Amy and Leo references. Amy sits on the left side of a bench with an open storybook on her lap. Leo sits beside her on the right and looks at the pages. Amy points to a picture. Keep their original faces and outfits. Use the park setting from the earlier scene.

The character references and outfit details stay the same in each example. Only the setting, position, and action change.

How to Fix Mixed-Up Faces, Outfits, and Positions

Even with the right method, a few common mistakes can derail your results:

Keep Each Character's Details Together

Instead of 'two children wearing blue and red,' write 'Amy wears a blue coat. Leo wears a red striped shirt.' Give each character their own sentence when assigning clothes, props, or actions.

State Who Goes Where

Unclear: 'Amy and Leo are together'. Clear: 'Amy stands on the left side of the image. Leo sits on the right'.

Remove Conflicting Instructions

Check for details that contradict the references. If Amy's reference shows a blue coat, don't also ask for a red jacket unless the outfit change is intentional. Remove actions that ask the same character to do two things at once.

Use References That Show the Important Details

Choose references where faces, clothing, and accessories are easy to see. If shoes matter in the scene, use a reference that includes them. Replace blurry or badly cropped images before trying the scene again.

Fix the Wrong Detail Without Starting Over

Send the scene to Editor Pro and name the correction: 'Change only Amy's coat to blue. Keep Leo, both faces, their positions, and the background unchanged.' Check the result before saving it. If you need exact placement, arrange separate character images in Canvas.

Step 4: Keep the Same Characters Across Storybook Pages

Use the same character references for later pages. Compare every new scene with those references before making it the starting point for another edit.

Save Approved Characters and Scenes.

Favorite or pin the character images you want to reuse. Save scenes after checking faces, outfits, accessories, and relative height. When continuing a scene in Editor Pro, start from an approved image so you don't carry an earlier mistake into the next page.

Match the Illustration to Your Book Size

Choose your book size in Canvas before laying out the pages. Use Reframe if an illustration needs a different shape; don't stretch it. Leave space for story text and keep faces away from the center fold of a spread.

Tip 3: Build complexity gradually

For complex scenes with specific interactions, sometimes it helps to generate a simpler version first, then iterate toward the final vision. Going from "standing together" to "playing catch" to "playing catch while laughing in the rain" in stages often produces better results than jumping straight to the complex version.

Reuse the Setting and Style

When a scene continues in the same place and time, reuse its background and lighting. In Story Scene Pro, click Add, choose Style, and upload your style reference. Use the same style image for later pages. Change the lighting when the story calls for it, such as moving from afternoon to night.

Check Both Characters Before Moving On

Compare each face, hairstyle, outfit, and accessory with the original references. Check who holds each object and whether the characters' heights still make sense. Use Editor Pro for a specific correction, or regenerate if the whole scene needs another attempt.

Once the scenes are ready, add text in Canvas and assemble the pages in Projects. Follow the guide to making a children's book with AI for layout and export.

Frequently Asked Questions

How many credits does each generation cost?

Each image generation or edit costs 4 credits. A new account includes 20 free credits, enough for five operations. If you create two character references first, those use 8 credits, leaving 12 credits for three scene generations or edits.

Can I reuse the same characters in another book?

Yes. Save your approved character references and reuse them in later projects. If a character needs a new outfit, save that version separately so you can choose the right reference for each story.

What if my characters need to change outfits?

Use Outfit Editor to create the new outfit, then save that image as the reference for scenes where the character wears it. Check that the face and hair still match the original.

Can I use my own drawings or characters from another AI tool?

Yes. You can upload your own character images as references. Choose clear images that show the face, outfit, and any details needed in the scene. Use artwork you have permission to use.
